Cold extrusion is typically used for metals that are easier to cold work, such as steel and brass. The text was updated successfully, but these errors were encountered:. There's a temp fall error catch that will disable the extruder power in the event of a drop off (like if the thermistor fell out) Once it gets below the safe extrusion temp it won't allow it to extrude anymore. For next time, there are dummy temperature sensors in Configuration. Simply speaking, in the process of making bolts, hexagonal head forming belongs to cold upsetting, and rod diameter reduction belongs to cold extrusion (forward extrusion). It is found that at low temperature. In Marlin is a disabled feature // # define EXTRUDE_MINTEMP 170.
